Abstract

Die Erfindung geht aus von einer Vorrichtung (2) zur Aufnahme von Bildern einer Objektszene (4) mit einer Beleuchtungseinheit (6) zum Beleuchten der Objektszene (4) mit mehreren Beleuchtungselementen (14) und einer Optik (10) zum Lenken von aus der Objektszene (4) reflektierter Strahlung der Beleuchtungselemente (14) auf einen Detektor (8).The invention is based on a device (2) for taking pictures of an object scene (4) with a lighting unit (6) for illuminating the object scene (4) with a plurality of lighting elements (14) and an optical system (10) for directing out of the object scene (4) reflected radiation of the illumination elements (14) onto a detector (8).

Um eine einfache und kompakte Kamera zu erreichen, wird vorgeschlagen, dass die Vorrichtung ein Markiermittel (18) umfasst zum Markieren der Strahlung aus jedem der Beleuchtungselemente (14) und ein Auswertemittel (20) zum Unterscheiden der reflektierten Strahlung der einzelnen Beleuchtungselemente (14) anhand der Markierung.
